Telehouse North Latency Issues 4PM - 8PM

So I was seeing some issues last week when connected through PTN-BNG01&02 which then stopped as soon as I moved to PCL/PTW gateways... I ended up back on a PTN gateway again yesterday and the issue returned.. I have raised a ticket about the issue but thought I would see if anyone else is having these issues too?This is an example from the 15th AprilThis was yesterdays (21/04)
